Description

Technical Field

[0001] The utility model relates to the technical field of forklift ejectors, in particular to a rotary ejector for a forklift. Background Art

[0002] Forklift ejector is a forklift auxiliary equipment specially designed to meet the needs of loading and unloading goods, transportation, etc. It is widely used in various places that require cargo handling and stacking, such as factories, warehouses, docks, logistics centers, etc.

[0003] Different types and structures are selected according to different forklift models and the application requirements of the on-board equipment. One type is a rotary ejector, which is used to move goods from the pallet to locations such as trucks or warehouses. When in use, the goods and pallet are separated by rotation to achieve the purpose of transportation.

[0004] Existing rotary ejectors typically have side guards to protect the side space and prevent cargo from falling. However, since cargo needs to be pushed from the ejector to the transport location, most rotary ejectors lack a protective structure on the front. When transporting loose cargo, the cargo may fall through the front opening during the flipping process. To address this issue, we propose a rotary ejector for forklifts to effectively address this drawback. Utility Model Content

[0013] Compared with the prior art, the present invention provides a rotary ejector for a forklift, which has the following beneficial effects:

[0014] The utility model installs two flip plates that can rotate around the front sides of the side panels on the front of the ejector, and fixes a rotating rod and a gear on the flip plates. When the side panels move from both sides to the middle, the gear will be driven to rotate by the rack in the transmission component, thereby driving the flip plates to flip to the front of the ejector, thereby protecting the front and preventing goods from falling from the front opening during the flipping process; at the same time, when the side panels move to both sides, the flip plates will flip and open to both sides, thereby not causing any obstruction to the pushing out of the goods.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figures 1-4 A rotary ejector for a forklift includes a transport fork 1, a push plate 2 being slidably provided on the upper surface of the transport fork 1, and vertically distributed lifting cylinders 3 being fixedly provided on both the left and right sides of the upper surface of the transport fork 1. The free ends of the two lifting cylinders 3 are commonly connected to a pallet fork 4, so that the lifting cylinders 3 can drive the pallet fork 4 to rise and fall, thereby changing the height of the pallet fork 4 and enabling the pallet fork 4 to lift the pallet. Side plates 5 are movably provided on the left and right sides of the transport fork 1, and a flip plate 6 and a rotating rod 8 are rotatably provided on the front sides of the two side plates 5. The flip plate 6 and the rotating rod 8 are fixedly connected, and the side plates 5 and the rotating rod 8 are rotatably connected. The bottom end of the rotating rod 8 extends below the side plate 5 and is fixedly fitted with a gear 801, so that the gear 801, the rotating rod 8 and the flip plate 6 rotate together, thereby causing the flip plate 6 to flip around the rotating rod 8 on the front side of the side plate 5.

[0022] Furthermore, transmission assemblies 7 for rotating the flip plate 6 are provided on both the left and right sides of the transport fork 1. The transmission assembly 7 includes a guide rail 701 and a rack 702. The guide rail 701 is U-shaped so that the guide rail 701 can protect both sides of the gear 801. The gear 801 extends into the inner side of the guide rail 701, and the rack 702 is located on one side of the inner side of the guide rail 701 and is adapted to the gear 801. When the side plate 5 moves to the sides, it will drive the rotating rod 8, gear 801 and flip plate 6 to move to the sides. When the gear 801 moves to the position of the rack 702, it will be driven by the rack 702 to start rotating, thereby driving the rotating rod 8 and flip plate 6 to rotate, causing the flip plate 6 to flip to the side of the side plate 5, thereby achieving the purpose of opening the front of the ejector and avoiding obstruction of the goods during unloading.

[0023] Furthermore, a torsion spring 802 is sleeved around the outside of the middle portion of the rotating rod 8, with the upper and lower ends of the torsion spring 802 fixedly connected to the rotating rod 8 and the side panel 5, respectively. A tubular connecting sleeve is welded to the sidewalls of both the side panel 5 and the rotating rod 8, and the connecting sleeves on the rotating rod 8 and the side panel 5 respectively sleeve onto the upper and lower ends of the torsion spring 802, thereby fixing the upper and lower ends of the torsion spring 802 to the rotating rod 8 and the side panel 5, respectively. In its natural state, the torsion spring 802 is in a contracted state, at which point the flip panel 6 flips to the front of the side panel 5, achieving a closed state. When the side panel 5 moves to the sides, the flip panel 6 flips to the side of the side panel 5, twisting the torsion spring 802. This causes the flip panel 6 to flip back to the front when the side panel 5 moves toward the center the next time, due to the action of the torsion spring 802.

[0024] Furthermore, a rotating connector 9 is fixedly mounted on the back of the transport fork 1. This connector 9 and the pallet fork 4 slide vertically together to provide greater stability during the lifting process. The rotating connector 9 is a hollow structure, and a bidirectional cylinder 901 is fixedly mounted within the rotating connector 9 for driving the two side panels 5 to move laterally. This allows the bidirectional cylinder 901 to drive the two side panels 5 to move simultaneously toward each side or toward the center, thereby synchronizing the flipping of the two flip plates 6. A scissor assembly 201 is also provided between the rotating connector 9 and the push plate 2, which is used to push the push plate 2 along the length of the transport fork 1, providing power for its movement, thereby pushing the cargo outward and completing its transfer.

[0025] The working principle and use process of the utility model are as follows: first, the pallet fork 4 is flipped to the lower position, and the pallet fork 4 is controlled to enter the pallet to lift the pallet. At this time, the goods will also be lifted. When the goods are lifted to contact with the carrying fork 1, the two-way cylinder 901 drives the two side plates 5 from both sides to move closer to the goods in the middle. When the two side plates 5 contact the goods, the gear 801 at the bottom of the rotating rod 8 will first pass through the rack 702 in the transmission assembly 7, causing the gear 801 to rotate, driving the rotating rod 8 and the flip plate 6 to rotate. When the gear 801 moves to At the flat position in the guide rail 701, the flip plate 6 will flip to the front position. Due to the action of the torsion spring 802, the flip plate 6 will not shake. At this time, the pusher can be controlled to start rotating as a whole, so as to prevent the goods from falling from the front opening, and finally the pallet fork 4 is flipped to the top. Then, the pallet fork 4 is controlled by the lifting cylinder 3 to drive the pallet to rise. At this time, the goods are located on the upper surface of the carrying fork 1, and then the side plates 5 are controlled to move to both sides to open the flip plate 6. Then, the scissor fork assembly 201 is used to drive the push plate 2 forward to push the goods out to complete the carrying operation.
